Midrash sobre Proverbios 6:35

A parable—To what is the matter comparable? To a man who wished to take a voyage at sea. If he did not take with him bread and water from an inhabited land, he will not find anything to eat or to drink on the sea. Again, || if a man wish to go to the end of the wilderness, unless he take from some inhabited place bread and water, he will not find anything to eat or to drink in the wilderness. Likewise, if a man did not repent in his lifetime, after his death he cannot repent. But (God) gives to a man according to his ways, as it is said, "I the Lord search the heart, I try the reins, even to give every man according to his ways, according to the fruit of his doings" (Jer. 17:10).
